一种用于关口电能表现场检验的智能接线盒及检验方法
摘要：
本发明公开了一种用于关口电能表现场检验的智能接线盒，系统包括：转换单元、模数转换单元、信号编码与电光转换单元以及校验仪。电转换单元，用于将电压/电流互感器二次回路电压、电流信号转换为低电压信号。模数转换单元，用于接收低电压信号，将低电压信号转换为数字信号。信号编码与电光转换单元，用于接收数字信号，将数字信号转换为电光信号，并将电光信号输入校验仪。校验仪，用于将电光信号转化为计量电量，并与被检电能表电量进行对比，获取电能表的误差。
摘要（英）：

The invention discloses an intelligent junction box used for gateway electric energy meter field inspection. The system comprises a conversion unit, an analog-to-digital conversion unit, a signal coding and electro-optic conversion unit and a calibrator. The electric conversion unit is used for converting voltage/current transformer secondary loop voltage and current signals into low voltage signals. The analog-to-digital conversion unit is used for receiving the low voltage signals and converting the low voltage signals into digital signals. The signal coding and electro-optic conversion unit is used for receiving the digital signals and converting the digital signals into electro-optic signals and inputting the electro-optic signals to the calibrator. The calibrator is used for converting the electro-optic signals into metering electric quantity and comparing the metering electric quantity with the electric quantity of the inspected electric energy meter so as to acquire the error of the electric energy meter.
